IMPROVEMENT IN SAW -SETS.

Specification forming part of Letters Patent No. 209,222, dated October22, 1878; application filed March 25, 1878.

To all whom 'it may concern:

Be it known that I, FRANK A. BUELL, of Brooklyn, E. 1)., in the countyof Kings and State of New York, have invented a new and ImprovedSaw-Set, of which the following is a specification:

Figure 1 is a side elevation of my improved saw-set. Fig. 2 is alongitudinal section taken on line as a: in Fig. 1.

The invention will first be described in con- I nection with thedrawing, and then pointed out in the claim.

Similar letters of reference indicate corresponding parts.

Referring to the drawing, A is a shank fitted to a handle, B, and havinga slot, (1-, which extends from its outer end toward the handle, and isregulated as to width by the bolt 1), which is provided with a wing-nut,0.

end of each jaw formed by slotting the shank is triangular, and fromeach jaw short arm 0; projects at an angle of about forty-five degrees:1

These arms are oppositely arranged in respect to each other, and areeach provided with a gage-screw, d, which passes through the arm at aright angle, and projects toward the center line of the shank. A gage,6, formed of sheet metal and having a straight lip, f, is fitted to theslot in the shank, and is slotted to allow the bolt b to pass through. Asetscrew, 9, passes through one of the jaws of the The shank, and clampsthe gage 0 against the opthe teeth to be set, and the gage-screws areadjusted so that when the saw-tooth is secured between the jaws of theset it may be bent by moving the instrument until the gagescrew touchesthe saw-blade. It is then placed on the next tooth and moved in theopposite direction in the same manner, and so on until all of the teethin the saw are set.

By means of my improvement the teeth of saws may be uniformly andrapidly set.

1 am aware that it is not new to use a shankbar with handle, and with atoothed wheel and gage-arm in an offset, with suitable clamps, so thatthe teeth of a saw may be set in each direction without reversingtheinstrument or saw; but

*VVhat I claim is- The forked shank A, having the adjustingbolt b andarms 0, provided with the gage- .screws d, substantially as and for thepurpose specified.
